Application filed october `1,1 192e. serial No. 138,967.

This invention relates to an improved apparatus for simultaneouslypressing the dents in a plurality of bakery rolls, which is illustratedon the accompanying drawing,

in which:

Fig. l is a perspective view of the same, with part of the outer casingbroken away to show the inner mechanism of the apparatus,

Fig. 2 is an end view of part of said mech anism, Y

Fig. 3 is a longitudinal section through. part of the apparatus, and

Fig. 4 is a cross-section throughy a detail of the same on a largerscale.

The apparatus comprises an outer casing a of wood or metal.' Within saidcasing, a pressure-plate Z) is arranged. .On the upper side of thelatter, two vertical toothed l0 racks c are fixed at a distance from oneanother and led through guiding-slots inthe the top of said casing andthrough openings in a guiding-ledge i fixed in the latter, while on ahorizontal revoluble shaft Zin said casing two pinions 7L are keyed andin gear with said toothed racks. Said shaft `Z projects at one endbeyond the casing a and carriesl there a wheel g with a crank-handle f,by which the shaft can be rotated and'thus the pressure-plate can bemovedV up and down. On each of two opposite ends of Y said j)ressure-plate Zia plurality of, for instance six, depending brackets Zoare fixed by means of nuts VZal screwed above and below lsaidpressure-plate on a screw-threaded part of said brackets, so that theposition of height of thel latter can be easily adjusted by means ofsaid nuts. Each two oppositebrackets 7s carry at their -lower ends arevoluble pressure-har Z. v

As shown in Figs. 3 and 4, between the pressure-plate Z) and eachpressure-barZ an oil bolster ais suspended loosely from the brackets 7cso as to bear at its underside directly upon the pressure-bar Z, an oilcontainer o (Fig. 4) being located on the pressure-plate Z) Vandprovided with very narrow depending supply pipes o1 which feed the oilin drops to the upper groovedoil-perme able surface nl of said bolsters,whereby the pressureebarsZ are slightly'lubricated in a continuous way.j For sakeV of clearness, the

oil container 0 `with its supply pipeso1 has been omitted lfrom Figs. 1and 3. The lower surface of the oil bolsters is concave,

while belowthe adjacent Vsides of each two oil bolsters a gutter p isprovided for the reception of the'excess oil dropping fromsaidb'olsters, said gutters preventing at the .same time a sticking oftheroll .fr to the vpressure-bar Z during the ascent of the latter vafter having` pressed the .dent in the roll.

For this purpose, the rolls m, Vwhich are placed in grooves r of a boardg upon Which said Igutters are fixed, are of correspondingk nr ovarica;

length so that they abut with theirv ends v against the underside ofsaid gutters in case that they are unintentionally lifted with thepressure-bars I by j board q' can be laterally inserted in andremoved`from the casing through a slot therein (not shown) and placed upon thebottom s of thelatter.

The rotation of the pressurewbars Z, during the up and` down movement ofthe same together with the pressure-plate Z), is effected by means ofpinions t keyed onv the outwardly `projectir'ig ends of saidv bars, the

sticking y thereto. The .7'

outermost of said pinions being in gear with a toothed-rack lined to theoutside ofthe casing a, while the projecting ends ofjsaid presure-barsare guided in vertical slots fv in said casing, Y.

The operation isas follows: By turning the crank handle f in onedirection` vthe pressure-plate ZJ together with the well ludesired dentsare pressed in the rolls m, while by a rotation of the crank handle fbricatedpressure-bars Z are'lowered with a.

simultaneous rotationof the latter until the l inthe opposite direction,the presure-plateV n with the pressure-bars are again lifted. e

What I claim, is: l v 1. The combination, in .an apparatus forsimultaneouslyv pressing dents in a plurality of bakery rolls, of up anddown movable and loosely suspended oil holsters in direct Contact Withsaid pressure-bars during the up and down movement of the latter.

2. In an arrangement as specified in .claim l, means for separatelyfeedingy each oil bolster with oil.

3. IIn anfarran'gementasspecified in claim 1, means for collecting theexcess oil dropping from said oil holsters and at the same timepreventing the rolls from sticking t0 the returning pressure-bars aftertheir treatment. Y

In testimony whereof I have hereunto set my hand.
